U1 and U2-Mini review quotes

Draws the very best aspects from throughout the LUMIN range

New processing hardware and software first introduced with the U2-Mini and T3

The best features used from our flagship players such as Fibre Networking, Linear Power Supply and Dual-stage voltage regulators

New for a LUMIN Transport - U2 uses CNC panel construction finished in a new silky surfacing process taken from our high-end P1 that is less susceptible to finger marks and easier to clean.
